Abstract Eight new species of Desmopachria Babington, 1841 are described and illustrated from Brazil: D. dicrophallica sp. nov., D. disticta sp. nov., D. grammosticta sp. nov., D. grandinigra sp. nov., D. itamontensis sp. nov., D. leptophallica sp. nov., D. stethothrix sp. nov., and D. ukuki sp. nov. The species D. amyae Miller, 2001, D. chei Miller, 1999, D. margarita Young, 1990, and D. volatidisca Miller, 2001 are recorded for the first time from Brazil. From species of the Desmo- pachria reported in Brazil, D. aldessa Young, 1980 has a new record from Pará state and D. fossulata Zimmermann, 1928, D. granoides Young, 1986, and D. laevis Sharp, 1882 have new records from Rio de Janeiro State. A checklist of all Desmopachria recorded from Brazil is presented with notes about some of the localities.

As espécies D. amyae Miller, 2001, D. chei Miller, 1999, D. margarita Young, 1990 e D. volatidisca Miller, 2001são registradas pela primeira vez para o Brasil. Das espécies de Desmopachria registradas para o Brasil D. aldessa Young, 1980 tem um novo registro para o estado do Pará e D. fossulata Zimmermann, 1928, D. granoides Young, 1986 e D. laevis Sharp, 1882 têm novos reg- istros para o estado do Rio de Janeiro. Uma listagem de todos os Desmopachria registrados para o Brasil é apresentada, com notas acerca de algumas localidades.
